This Technote is very helpful, but I fail when trying to create the
suggested PixelBuffer with
err = CVPixelBufferCreate(NULL, width, height, k8IndexedGrayPixelFormat, nil, &tmpPixBuf);
the undocumented error is err==-6680.
But only when I use k8IndexedGrayPixelFormat (and that is what I need).
It does work with k32ARGBPixelFormat.
Any idea what could be going wrong?
Greetings
